Ukrainian Radical Party

The Ukrainian Radical Party (URP) was a socialist political party in Ukraine that was active from 1890 to 1939. The party was formed to represent the radical movement in western Ukraine under a single banner, and it was the first modern Ukrainian political party with a defined program, mass following, and registered membership. The party advocated for socialism, increased rights for Ukrainian peasants, and secularism, and it was rivals with the nationalist UNDO party. The URP was dissolved when the Soviet Union annexed western Ukraine in 1939 during World War II.
